Abstract
A memory management unit may send page table walk requests to a page table descriptor in a main memory system and receive address translation information, with the page table walk requests including information that specifies an amount of further address translation information, and receive the further address translation information. The cache unit may intercept the page table walk requests, and modify content of the intercepted page table walk requests so the information that specifies the amount of further address translation information is extended from a first amount to a second amount greater than the first amount. The cache unit may store the second amount of further address translation information for use with data requests that are subsequent to a current data request, and provide the address translation information based upon an intercepted page table walk request being associated with address translation information already stored in the cache unit.
